`IVIACJEIINJE! FOR EXTERMINATING BOLLeWEEVILS.

To all 'whom t may concern.'

Be it known that I, IsAAc TUs, a citizen of the United States, residingat Piggott, in the county of Clay and State of Arkansas,

have invented new and useful Improvements.

in Machines for Exterminating Boll-Weevils, of which the following is aspecication.

The object of my present invention is to provide a simple, easilyoperated and efficient machine for mashing and thereby destroying bollweevils.

To the attainment of the foregoing the invention consists in thepeculiar construction, novel combinations and adaptation of parts ashereinafter described and definitely claimed.

In the accompanying drawings which are hereby made a part hereof:

Figure 1 is a side elevation of the machine constituting the bestpractical embodiment of my invention that I have as yet devised.

Fig. 2 is a top plan view of the same.v

Fig. 3 is a rear elevation of the machine.

Fig. 4 is an enlarged detail section showing the relative arrangement ofthe guard employed in conjunction with the internal gear on one mashingwheel.

Fig. 5 is a detail transverse section taken through the blower of themachine.

Fig. 6 is a detail view of the clutch intermediate of one of the mashingwheels and the blower fan.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The main frame 1 of my machine may be of the construction shown or ofany other construction compatible with the purpose of the invention. Theforward portion of said frame is connected to an axle 2, bearing groundwheels 3 and adapted for the connection of draft animals when suchanimals are to be employed for the movement of the machine.

The rear portion of the frame 1 is supported upon axles 4, and isequipped with a drivers seat 5. The axles 4 carries mashin wheels 6which are spaced apart and are quite heavy. The treads of the wheels 6are made comparatively wide, and in the pre` ferred embodiment of theinvention the said wheels are eighteen inches in width by fortyeightinches in diameter.

Opposed to the upper rear portions of the perimeters of the wheels 6 arescraping.

blades 17 which are designed to serve the improved purpose of. keepingthe perimeters clear of dirt-and other substance with a view tomaintaining the efficiency of the wheels in mashing boll weevils. Thesaid scrape blades are connected by arms 8 to rock shafts 9 which arejournaled in suitable bearings on the frame 1 and are provided withpedal levers 10 arranged in convenient proximity to the drivers seat 5.

At 11 on the frame 1 is carried the casing of the blower, the saidcasing containing a blower fan 12, and being equipped with a dischargespout 13 which is carried downwardly and has its eduction orificearranged at the inner side of the right hand fender as best shown inFig. 3.

The fenders 14 are connected through suitable hangers 15 with the mainframe and have their forward ends iiared as illustrated. The purpose ofthe fenders is to move at opposite sides of the plants so as to protectthe limbs or branches, especially the lower limbs or branches of theplants from the mashing wheels 6.

One of the mashing wheels 6 and preferably the right hand mashing wheelis equipped with an internal gear 16, and the said internal gear 16 isconnected through a train of gears 17 with the shaft of the blower fan12; the said gearing being of such type as to powerfully rotate theblower fan at a high rate of speed during the traverse of the machine.

Included in the said train of gearing is a clutch, one member 17 ofwhich is connected as shown with a pedal lever 18 so that when the saidlever 18 is. pressed forwardly the clutch member 17 will be movedagainst the action of its spring 19 so as to interrupt the drivingconnection intermediate the right hand mashing wheel and the blower fan12.

At 20 is a guard designed and adapted to prevent portions of the plantsfrom being caught in and injured by the teeth of the gearing 16. Thesaid guard is connected with and carried by the shaft of the right handmashing wheel.

It will be apparent from the foregoing that my novel machine is adaptedto straddle the row of plants, and the fenders 14 are so arranged as toadequately protect the plants from the mashing wheels. Incidental to thetraverse of the machine alon the row the blast of air under pressure romthe eduction orifice of the spout 13 serves to displace the bolls frompoints about the stalks of the plants into the paths of the wheels,

whereupon the wheels will pass over and mash or crush the bolls with theresult that the boll weevils Will be e'ectively exterminated. It willalso be apparent that the boll weevils on the ground and in. thepaths ofthe wheels will not be displaced by the blast from spout 13.

The construction herein shown and described is the best reduction topractice of my invention that I have as yet devised, but I wouldhave itunderstood that in the future practice of the invention various changesin the form and relative arrangement of the parts may be made within thescopel of my appended claims.

Having described my invention what I claim and desire to` secu-re byLetters Patent is:

l. A straddle-row boll weevil exterminating machine, comprising spacedmashing wheels, and air-blast means for displacing boll weevils fromabout the stalks of the the paths ing machine, comprising spacedmashingl wheels, spaced fenders for protecting the plants from thewheels, and air-blast means for displacing boll weevils from about thestalks of the plants and moving4 the same into the paths of the wheels.

3. A straddle-row boll Weevil exterminating machine comprising a frame,steering wheels connected therewith, comparatively wide 'andl spacedmashing wheels connected with the` frame, an internal gear in one ofsaid wheels, a guard in the wheel and complementary to` the gear, ablower casing carried by the frame and having a depending dischargespout, fenders spaced apart and carried by the frame at the inner sidesof the mashing wheels, and a rotary fan inI the blower casing andconnected through a gearing withv the internal gear of one mashingwheel.

In testimony whereof I aflix my signature.
